越来越多的证据表明，对不确定性的不容忍（IU）是一种认知脆弱性，是包括广泛性焦虑症（GAD）在内的各种焦虑症的核心特征。虽然认知行为疗法（CBT）已被证明可以减少IU，但IU的减少是否会减轻焦虑仍有待确定。本研究考察了28名完成CBT的GAD患者的IU和担忧变化过程。使用多层次中介模型分析治疗期间每两周评估一次的IU和担忧的变化。结果显示，IU的变化介导了担忧的变化（ab = -0.20; 95% CI [-0.35，-0.09]），但担忧的变化不介导IU的变化（ab = -0.16; 95% CI [-0.06，.12]）。研究结果表明，在治疗过程中观察到的担忧减少中，IU的减少占59%，这表明IU的变化不仅仅是担忧变化的伴随物。研究结果支持的想法，IU是一个重要的结构基础广泛性焦虑症。
Growing evidence suggests that intolerance of uncertainty (IU) is a cognitive vulnerability that is a central feature across diverse anxiety disorders, including generalized anxiety disorder (GAD). Although cognitive behavioral therapy (CBT) has been shown to reduce IU, it remains to be established whether or not reductions in IU mediate reductions in worry. This study examined the process of change in IU and worry in a sample of 28 individuals with GAD who completed CBT. Changes in IU and worry, assessed bi-weekly during treatment, were analyzed using multilevel mediation models. Results revealed that change in IU mediated change in worry (ab = -0.20; 95% CI [-.35, -.09]), but change in worry did not mediate change in IU (ab = -0.16; 95% CI [-.06, .12]). Findings indicated that reductions in IU accounted for 59% of the reductions in worry observed over the course of treatment, suggesting that changes in IU are not simply concomitants of changes in worry. Findings support the idea that IU is a critical construct underlying GAD.
